IMPROVEMENT IN COOKING-RANGES.

Specification forming part of Letters Patent No. 168, 152, dated September 28, 1875; application filed November 12, 1874.

Tofall whom it may concern.- Be it known that I, THRUsrA s GRooM, of the town'of Guelph,Provinceof Ontario, Ganada, have invented newand useful Improvements in (looking-Ranges, of which the following is a specification:

My invention relates to improvements in the ordinary ranges used for cooking in hotels and private houses; and it consists in certain featureshereinafter fully described.

Certain other features and devices, are herein illustrated and described, which, however, do not form a part of the invention claimed herein, but which may form the subject-matter of other applications.

In the accompanying drawings, Figure 1 is a longitudinal section through a range embodying my improvements. Fig. 2 is a crosssection of the same. Fig. 3 is a front View of the range whenclosed up in cooking. Fig. 4. is a front view with oven-doors open and smoke-disperser raised. Figs. 5 and 6 are details, respectively, of the cleaning-out doors and grate-bar holders.

A and A are the two divisions of the range, placed one on each side of the fire-place O. B are the ovens; b, the shelves therein. 0b are the doors of ovens. O is a flue leadingfrom fire under the hot-water reservoir 0 to the rear, the smoke, &c., escaping through the c is the grate. c are fire-brick walls, placed to screen the metal of ovens from' the direct heat of the fire, and molded to lap over 'the corners of ovens. D, the ash-pan.

D is the ash pit;

cess in which the range is fitted, and which form one side of the hot-air chambers to, the other sides being the cast-iron partitions a w are they collars upon which the hot-air con 00 are dampers for admitting cold air. F are pipes for conducting airfrom the exterior of range to the interior of ovens, the inlet being placed near the F is a damper placed on the roof of ovens for regulating the exit of The dampers and ports'are covered with suitably-shaped hoods fordirecting the draft in the proper direction. j. is a rod pass ing from the damper to the outside of range,

by means of which the operator is enabled to regulate the ventilation of the ovens. His the smoke-disperser, constructed in the manner shown, to slide forward. It is the door, which slides up and down on H, and may be secured in any desired position on H by a spring-latch fitting into the notches h. when roastingor baking, the range being closed up, the disperser is shoved back and the door it is drawn down.

Wheuthe range is used as an open fire, the disperser is drawn forward to its full extent and the door shoved up, as shown in Fig. 4.

l and I are the grate-bar holders, projecting outward from the front of range, and in 'which the grate-bars I are fastened by slipping one end into the circular hole i, the other end fitting within the slot 1;.

It will be seen from an inspection of Fig. 6 that-all or each of the bars can be removed readily when requiring to be cleaned, or for the purpose of raking out the fire-place.

J is the cock on the end of hot-water pipe leading from the reservoir 0 A are the cleaning-out doors of the flues. These doors are constructed with a lip,- 0. on lower edge, which fits over the lower edge of opening,

'and acts as a hinge, the door being kept closed in place by the weight of the {counterbalance a on the end of the handle 0?. K are dampers used in regulating the discharge of smoke, 850., through the fines, and also for changing the draft through the range. E are the walls of the re- The draft of the fire may be caused to pass either over the ovens and out through the dues m and m or it ma be caused to ass u 7 y p at once under the smoke-disperser H by manipulating the dampers K.

When passing, as in roasting or baking,

over the ovens, the draft naturally carries with it the fumes which arise during the cooking of meats, and takes them off up the chimney, the hoods over the ports preventing the smoke from entering the oven.

Of course, I do not confine my improve" 'ments to any particular style of oven, they.

being applicable to all kinds of ranges with single, double, or more ovens.
